I don't think there's a rule against rolling the ball to a batter; it would be called a ball. It would be similar to a wild pitch or an intentional walk (when you had to actually throw the 4 balls).

I'm beginning to feel like Americans trying to understand cricket trying to understand the tactical permutations of intentional walks :D

The equivalent would be bowling a ball rather than a strike in a baseball variant where each innings ended after a fixed number of balls regardless of the number of outs (which is effectively what One Day variants of cricket are). Specifically, walking the batsman when they needed to score a home run or at least a double. I think fans would get upset!
